1. Cookies – what are they?

A “cookie” is a small text file that’s stored on your computer, tablet or phone when you visit a website. We may collect information from you by using “cookies”. A cookie will contain some anonymous information, such as a unique identifier and the site name, and some digits and numbers.

Some cookies are deleted when you close down your browser. These are known as session cookies. Others remain on your device until they expire, or you delete them from your device history. These are called persistent cookies and they help us to remember things about you as a returning visitor to our website.

2. How we use cookies

We use the following types of cookies on this website (the “Site”):

  • Strictly necessary cookies. These are cookies that are required for the operation of our website. They include, for example, cookies that enable you to log into secure areas of our website.
  • Functionality cookies. These are used to recognise you when you return to our website. This enables us to personalise our content for you, greet you by name and remember your preferences (for example, your choice of language or region).
  • Analytical/performance cookies. These are a type of persistent cookie (as explained in the “Cookies – what are they?” section above). They allow us to recognise and count the number of visitors and to see how visitors move around the Site when they are using it. This helps us to understand what people do and don't like about the Site so it can be improved, for example by ensuring that users are finding what they are looking for easily. Since Google started providing its own analytics technology free of charge to website owners, almost all websites use some form of it - although there are also paid-for services available to rival Google's service. Analytics cookies are probably the most common form of cookies in use today.
  • Targeting cookies. These cookies record your visit to our website, the pages you have visited and the links you have followed. We will use this information to make our website and the advertising displayed on it more relevant to your interests. [We may also share this information with third parties for this purpose.]

4.What to do if you don’t want cookies to be set

Some people find the idea of a website storing information on their computer or mobile device a bit interfering, particularly when this information is stored and used by a third party without them knowing. Although this is generally quite harmless, you may not, for example, want to see advertising that has been targeted to your interests.

If you prefer, it is possible to block cookies, by changing a setting within your web browser that allows you to refuse the setting of all or some cookies, or to delete cookies that have already been set. However, if you use your browser settings to block all cookies (including essential cookies), you may not be able to access all or parts of this website.
